A lightning rod or lightning conductor (British English) is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. If lightning hits the structure, it is most likely to strike the rod and be conducted to ground through a wire, rather than passing through the structure, where it could start a fire or ...

[1] The structure is the fifth-tallest completed building in the state , [ 2 ] and is also Ohio's tallest building that rises in the center of a city block . [ 1 ]
When lightning strikes a metal tower or strikes near a building containing electrical equipment, a large, rapidly changing magnetic field is generated. This magnetic field induces current onto power lines, often disrupting electrical service, and also induces current into other electrical conductors such as electrical equipment and even ...
Cloud-to-ground lightning. Typically, lightning discharges 30,000 amperes, at up to 100 million volts, and emits light, radio waves, x-rays and even gamma rays. [1] Plasma temperatures in lightning can approach 28,000 kelvins. Atmospheric electricity describes the electrical charges in the Earth's atmosphere (or that of another planet).

The tower dominated the Columbus skyline, which did not see significant high-rise construction until the 1960s, [34] though there was at least one major attempt to build another high-rise in the city in 1953. [35] The Lincoln-LeVeque Tower was the only building in Columbus taller than 300 feet (91 m) until 1962. [9]
